In this study, the effect of a high-speed AP 7.62 bullet on Ti6Al4V, AISI 4340, Inconel-718, AlSi10Mg and Al 6061 - T6 materials at different impact angles were investigated by using finite element package software LS-DYNA 971. 4340 was taken as material 850 m/s speed for ballistic investigation. Angle obliquity against plates has been in range 0-80º. Simulations carried out 5 degrees increment...

The use of material for implant bearing has a vital role in minimizing failures that endanger recipients. Evaluation contact pressure can be the basis selection and have correlations with wear contribute to need revision operations. current paper aims investigate three different metallic materials, namely cobalt chromium molybdenum (CoCrMo), stainless steel 316L (SS 316L), titanium alloy (Ti6Al...

The aeronautical industry constantly strives for efficient technologies to facilitate hole-making in CFRP/Ti6Al4V structural components. prime challenge this direction is excessive tool wear because of the different engineering properties both materials. Nanofluid minimum quantity lubrication (NF-MQL) latest technology provide synergistic improvement tribological and function during machining. ...

Laser micro bending process of Ti6Al4V square bar are carried out using a 3D thermo-mechanical finite element analytical model (FEM). The transient temperature fields, displacement fields, stress fields and strain fields are obtained and analyzed. The results show that the bending angel during laser micro bending process is in good agreement with experimental measurements. The effects of proces...

This paper mainly reports the wetting state of liquid droplets on a Ti6Al4V micro-nanoscale hierarchical structured hydrophobic surface. In this work, the detailed action mechanism of the secondary nanostructure in the hierarchical structure on the wetting-state transition (from the Wenzel state to the Cassie state) was revealed and discussed. The variation of micro-morphology of the sample sur...
